The Lower City Sewers is a location that you may reach once you make your way to the Lower City and serves a new area to explore, which even leads to the Undercity.
Certain quests require that you head to the Lower City Sewers and there are several things that you will find down there but reaching this location is the first step before you can explore.
Luckily, finding your way down into the sewers won’t be that difficult as there are multiple entrances that you may take going down.
Lower City Sewers Entrances
Manhole Near Basilisk Gate Barracks
To the side of the Basilisk Gate Barracks (near the Stormshore Tabernacle), you will find a manhole that can be used to access the Lower City Sewers.
Manhole Near Golbraith’s Home
This manhole is located near the front of Golbraith’s Home, which is the first building north of The Blushing Mermaid or west of Bloomridge Park.
Revealed Entrance To Guildhall
There is an entrance that leads to the Guildhall, which is led by Nine-Fingers and you can open it by pressing the button on the wall.
To avoid getting in trouble with the nearby locals, you may speak to Tusgront and convince him to let your party through with an Ability Check.
Hatch in Hidden Room Within Knights of the Shield Hideout
While you approach the Elfsong Tavern for the very first time in the Lower City, The Emperor will mention that his old hideout is nearby. (Visit The Emperor’s Old Hideout quest begins)
If you head to the Elfsong Tavern and make your way down the wooden stairs, you will find yourself in the Elfsong Basement where a secret entrance leads to the Knights of the Shield Hideout.
Behind the statue at the end is a passage that can be opened by pressing a button nearby, which will allow you to enter the Hidden Room.
Within the Hidden Room will be a door that has a hatch inside, which will lead you to part of the Lower City Sewers.
Pit Latrine in Heapside Prison
If you make your way into Heapside Prison, going through one of the doors will allow you to go down the Pit Latrine.
This will take you to one of the parts near the Lower City Sewers, which is near the area that you enter if you go down one of the Manholes near Basilisk Gate Barracks.
A Greasy Slimy Climb Down in Flymm Cargo’s Basement
If you manage to make your way into Flymm Cargo and survive the fight with the Worgs inside, you can find the entrance to Flymm Cargo’s Basement.
Once you are in the basement, you can make your way to the entrance to the Lower City Sewers called “A Greasy Slimy Climb Down.”
Gloomy Ascent in Cazador’s Dungeon
Once you have explored Cazador’s Dungeon, you will eventually find a hidden entrance that leads to the Lower City Sewers.
This can only be unlocked from Cazador’s Dungeon and will lead to the northern part of the sewers, which is near the Undercity Ruins waypoint.
Verdict
Several quests involve you heading to the Lower City Sewers, this includes Aid the Underduke, Return Rakath’s Gold, The High Harper, Rescue Orin’s Victim, and even Free Orpheus.
Exploring the Lower City Sewers early is a good way for you to find your way around later and some quests may start if you look around.
Not all entrances to the sewers are accessible right away but you can always enter through the Manholes for a quick way to get to this location.
